47.5.2.5 Parity Error

Each time a character is received, the receiver calculates the parity of the received data bits, in accordance with UART_MR.PAR. It then compares the result with the received parity bit. If different, UART_SR.PARE is set at the same time RXRDY is set. The parity bit is cleared when UART_CR.RSTSTA is written at 1. If a new character is received before the reset status command is written, PARE remains at 1.
